Man, I must be missing a trick here because I have what seems to be a perfectly sound proof in my head that this room is impossible. Which of the following are true and which are untrue?
1) At the start of the room, the only things I can do that have any effect on anything are stepping on the pressure plate at (14,17) or on the Force Arrow Token at (18,22)
2) If I step on the plate first, the Seep will move to (3,4) regardless of what I do, and no further.
3) If I step on the plate and the seep moves to (3,4), then the only thing left that I can do that will have any effect on anything is stepping on the token. However, I then unavoidably get sealed in and can never step off the token.
4) If I step on the token first instead of the plate, I can't do anything until the bomb goes off. When that happens, there's no way I can ever move the seep or kill it.
5) Therefore, the room is impossible.
Edit: Oh man, stumbled upon the solution seconds after posting. I'd completely forgotten that

×Seep will preferentially move horizontally if your horizontal distance from them is greater than your vertical, rather than always preferring vertical movement when you're not in line with them horizontally and the diagonal is blocked like other monsters do.
